摘　　要：随着骨缺损患者数量的增加,其临床修复面临巨大挑战。传统自体骨移植法受限于术后感染风险,使得骨支架成为研究热点。三周期极小曲面(TPMS)骨支架因其独特的结构和优异的机械性能成为骨支架结构设计的优选。本文综述了TPMS骨支架在弹性模量、各向异性、壁面剪切应力、能量吸收性能和屈服强度等关键机械性能参数方面的研究进展。The prevalence of bone defects has surged,posing a great challenge to clinical repair strategies.The application of traditional autologous bone transplantation is limited by the risk of postoperative infections.In recent years,bone scaffolds have garnered considerable attention as a research hotspot for addressing the challenges of bone defect repair.Triply periodic minimal surface(TPMS)bone scaffolds have become the preferred choice due to their distinctive architecture and excellent mechanical properties.This article reviews the research progress on the key mechanical properties of TPMS bone scaffolds,such as the elastic modulus,anisotropy,wall shear stress,energy absorption,and yield strength.
